Oscilla (gastropod)
''Oscilla'' is a genus of very small sea snails, minute marine (ocean), marine gastropod mollusks or micromollusks. This genus is currently placed in the subfamily Chrysallidinae of the Family (biology), family Pyramidellidae.Rosenberg, G.; Gofas, S. (2011). Oscilla A. Adams, 1861. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=138415 on 6 July 2012 These marine gastropods have shells with intorted protoconchs. Life history Little is known about the biology of the members of this genus. As is true of most members of the Pyramidellidae ''sensu lato'', they are likely to be ectoparasites. ''Oscilla jocosa'' may possibly be a parasite on ''Trochus erithreus'' (Mienis 2003). Species of ''Oscilla'' The following species are mentioned in WoRMS: * ''Oscilla annulata'' (A. Adams in H. & A. Adams, 1853) * ''Oscilla appeliusi'' (Hornung & Mermod, 1925) * ''Oscilla aqabaensis'' Peñas, Rolán & Sabelli, 2020 * ''Oscilla aquil ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Oscilla Ficara
:For the genus of marine molluscs, see ''Oscilla'' (gastropod). ''Oscilla'' is a word applied in Latin usage to small figures, most commonly masks or faces, which were hung up as offerings to various deities, either for propitiation or expiation, and in connection with festivals and other ceremonies. It is usually taken as the plural of ''oscillum'' (diminutive of ''os''), a little face. As the ''oscilla'' swung in the wind, ''oscillare'' came to mean to swing, hence in English oscillation, the act of swinging backwards and forwards, periodic motion to and fro, hence any variation or fluctuation, actual or figurative. Many ''oscilla'' or masks, representing the head of Bacchus or of different rustic deities, are still preserved. There is a marble ''oscillum'' of Bacchus in the British Museum. Others still in existence are made of earthenware, but it seems probable that wax and wood were the ordinary materials. Small rudely shaped figures of wool, known as ''pilae'', were also hun ...

Oscilla Circinata
''Oscilla circinata'' is a species of sea snail, a marine (ocean), marine gastropod mollusk in the family (biology), family Pyramidellidae, the pyrams and their allies. Description The elongate-oval shell is subdiaphanous. It measures 2.1 mm. The Whorl (mollusc), whorls of the protoconch are small, almost completely immersed in the first post-nuclear whorl, only the rounded two-thirds of the last volution are visible, and those indicate that the axis of the nuclear turns must be at a right angle to the axis of the later whorls. The five whorls of the teleoconch are moderately well rounded, the last one somewhat inflated, shouldered. They are marked by strong, broadly rounded, subequal and subequally spaced spiral keels. These are separated by deep, rounded sulci, which are about as wide as the keels. The sulci are crossed by extremely fine and very closely spaced axial raised threads which pass up on the sides of the spiral keels, but do not cross their summits. The second a ...
